I wanted to thank everyone for their replies. Helpful. I built the U-Boat before the interior sets came out, and I've kicked myself ever since. I purchased the Gato within days of it's release and I'm foaming at the bit to dig into it, but don't want to do anything until interior sets are available. Guess I'll have to concentrate on finishing my 1/200 Yamato for the time being.
Again, thanks for all of your info.
Bob
